' PIPE-JOINT.

'y To all whom it may concern:

Be it known that I, ALFRED. R. FAInFmLD, a citizen of the United States, residing at Indianapolis, in the county of Marion and lState of Indiana, have invented a new andi useful Pi e-Joint, of which the following f ring 18, but too great an outward flow willl .is a speci cation.

The object of my invention is to produce a -Itting by means of which lead or otherf similar ductile pipe may be readily connect-v ed together or connected to other hollow elements suchas, stiff pipe, cylinders, trays, etc., being especially adapted for forming a connectionI between a. lead pipe and the side' wall of a'leact cylinder, sucl,` -for 'ilistance, as a lead trap. The accompanying drawing illustrates my invention. Y

The single figure of the drawing is an axial section, in partial elevation, of a fitting embodymg my invention and. designed to form a connection between a lead pipe and a lead trap, bent ferrule, drum trap, or

other` cylinder.` v

In the drawing, 10 indicates a mainltbular body having a bore 11 surrounded at onev end by a. curved annular seat 12the surface of vwhich may have annular roughenings if desired. The outer edge of the pocket 12 is overhung by an axially extendmg flange or wall 13 which is yintegral-With the main body and extends for a distance somewhat in excess of the thickness of the wall of the pipe 14 to be handled. The outer face oflan e 13 is provided with threads 15. adapter? to receive a clamping nut- 16. Thenut 16 is provided with an inwardly extending flange 1 7 which overlaps theadjacent pocket 12 .and engages a clamping ring 18' which, at its inner face 19, 1s

formed so as to mate with the bottom' of v war edge inserted into the flange 13, and

nut 16 threaded upon threads 15 and brought tightly to place, the flange 17 actinglupon portion 1 4l of the pipe 14 without any rubbing action. -The material of the flared portion 14of pipe 14 will, -under the pressure exerted flow so as to conform t0 the Patented Feb. 2o, 1912.

.'ring 18 todrivezitflrmly upon the flared u bottom of pocket 12 and the surface 19-of i bepr'evented because the end of the pipe will be definitely defined by -the inner corner of pocket 12. As a consequence, the', parts may be readily separated and reasi sembled to form a perfectly tight joint.y

The threaded pocket 21 vof the body 10 receives the threaded shank 22 ofa tubular lc'mplingihaving at its opposite end-f :flange 23 formed to4 fit the inner surface of the wall of a trap or cylindrical member 24.-

The member 24 is suitably perforated 'and the wall flared outwardly to form a flange 25 which will approximately fit the seat 26 formed in the corner between .flange 23 and the tubular shank of coupling 22. Threaded on the shank 22 is a` clamping nut 27 provided' with an annular pocket 28 for the reception of the outer edge lof the flange ber 24' so as to drive the material of Athe `badly ai tightly into Seat 26.

I claim as Smy invention: 1. A pipe coupling comprising a main tubular body having an annular pipe receiving pocket formed karound the end of the bore of the body, an axially extending flange A flanking the pocket at its outervside, a clamping ring projected into .thepocket within the-outer edge ofsaid flange and having an inner face. arranged to clamp the outwardly laredend of the pipe int-o the-pocket, means for Vdriving said clamping ring intothe pocket, a. tubular -coupling'member threaded into the said main body opposite the pipe `'receiving portion, an outwardly flaring flange carried by saidv coupling member at its opposite end andformed to fit the inner face of the cylindrical wall of another tu bular body adjacent an outwardly flared flange surrounding a perforation through said wall, ,a clamping n ut threaded upon the shank of said coupling member, and a clamping' ring rotatablyseated invsaid nut and provided with an inner face formed to coperaie with the coupling member and its Harige to clump the outwardly flared portion of the well of the cylinder surrounding the perforation thereof into the space between the tubular shank and Henge of said coupling member.

2. A pipe coupling comprising a main `tubular body having an annuler pipe receiving pocket formed around the end of the bore of the body, an axially extending flange flanking the pocket et its outer side, a clamping ring proj'eeed into the pocket within the outer edge of said enge and having an inner face arranged to clamp the outwardly flared end of the pipe into the pocket7 a demping nut threaded upon the main body and engegin the clamping ring' to drive the seme into t e .pockeue tubular coupling member threaded into the said main body opposite the pipe receiving portion, an outwardly flaring ange carried by Loieeli seid coupling member et its opposite end end formed to fit the inner face of the oylindricel wall of another tubular body adjecent en outwardly ared flange surrounding a perforation through seid wa11, a, clamping nut threaded upon the shank of seid coupling members und a clampingring rotatabiy seated in seid 'nut and provided with an inner face formed to coperate with the l coupling member and its dah e to clamp the outwerdlydiered portion o the Well of the cylinder surrounding the perforation thereof into the space between the tubular shankand Harige of said coupling member. In witness whereof, l have hereunto set my hand and seal al; Indianapolis, Indiana, this sevenihf'day of November, A. D. one khousend nine hundred and ten.
